Smart meters are under a fast development in line with overall digitalization that covers the energy sector. More applications, more rules and higher efficiency are resulting and therefore the “impact” of threats is driving developers to consider increasingly more the cyber security approach. Considering the personal data protection GDPR in force with May 2018, the concern about cyber protection and data privacy covers more and more areas. The architecture under this paper work (Unbundled Smart Meter under Role based Access Control) is presented compared with current applied solutions (like “DSO market facilitator” or “Independent central hub”, showing significant improvement from both perspectives: usage of meter data and cyber security, being also an advanced data handling approach compatible to a third data handling solution: the Data Access Point Manager concept.
